When this concept first came out, I predicted it would fail due to inaccessibility (the tiny hole) and the inability to upgrade lighting. Well, so far one of those points is out the window, I really didn't expect anyone to start DIY'ing one of these. We'll see how accessibility works out in the long run, seems like it might be an extra hassle to clean this thing, but I have only seen it in person once, yet. I did notice it had some decent dark spots all around, but that was stock lighting. Anyway, good job on the upgrades, guys, and good luck with the new tanks.
Are you not worried though that the heat from the light is going to melt the zap-strap that is against it?
If I can touch the light after a few hours running and not get burnt there is no way it will burn through and or melt a zip tie. Zip ties are pretty tough. The stock plastic light fixture is made to take the heat of the halogens that came with it so I'm not worried about that either.
Oh mygod, I love the light you added! Now I'm all excited! I'm going to be getting one of these for my CPDs, Deky Creek, and three Crystal red shrimp. I'm just drooling over these tanks! Now I know how to solve the low light problem. HUGS!!!
